Abstract
A technique for registering a device () with a rights issuer system () in a digital rights management (DRM) context is described. The device () is provided with DRM registration information that is required to use protected content. The DRM registration information is generated from rights issuer information on the one hand and device information on the other hand. The DRM registration technique described herein does not require an interactive registration protocol between a rights issuer server () and the device (). Rather, the DRM registration information may be generated and transferred to the device () even if the device () is offline, inactive or switched-off.
